Easy set of inexpensive squib rods:
From most any "home improvement" or decent hardware store, obtain two ~34" pieces of aluminum rod, 1/4" and 3/8" diameter, and a 2-pound hammer.
Cut each rod at 25" / 9". File off the sharp edges of the ends.
You now have pistol/rifle/shotgun squib rods for most calibers and common barrel lengths used in WBAS and CAS. The 2-pound hammer makes it easy to tap out a stuck slug with firm force yet plenty of control.
The rod sets can be stored in a section of pvc pipe, with one end cap glued on and another pressed on.
I keep a set in my cart, and it gets used often.
The rods are cheap enough to be considered an expendable item, versus wrecking someone's cleaning rod.
